Answer:

$181.19

Step-by-step explanation:

The coupon means you will pay 70% of the bill. The tax means you will pay 105.65% of the amount after the coupon is applied. Your final bill is ...

$245 × 0.70 × 1.0565 ≈ $181.19

_____

Your bill after the coupon is applied will be ...

bill - 0.30×bill = bill(1 - 0.30) = bill×0.70

The amount after tax is added is ...

charge + 0.0565×charge = charge(1 +0.0565) = charge×1.0565

Since the final bill is the product of these factors, the order of application does not matter. Conventionally, tax is applied last, so that accounting with the tax collection authority is properly maintained.

Determine the equation of the graph with the coordinates of (4, -1)

Anon25 [30]

Answer:

The required equation of the graph with the coordinates of (4, -1) will be:

$y=\left(x-4\right)^2-1$

The graph is also attached.

Step-by-step explanation:

Given the coordinates (4, -1)

If we put the coordinate values (4, -1) in the given equations, we determine that only $y=\left(x-4\right)^2-1$ is the valid equation as it satisfies the given coordinate value.

For example, putting (4, -1) in the equation

$y=\left(x-4\right)^2-1$

$\left(-1\right)=\left(4-4\right)^2-1$
